Launch of the program

• WebUI is now launched in the same powershell window as WebUI, with new logs and warnings at the start
• Fixed python error when there were spaces in the python path.

Warning

• This only works on Windows 10 and 11
• This has only been tested on Nvidia graphics cards (make sure you are up to date)
• This installer installs the original Automatic1111 Stable Diffusion WebUI repository but is not affiliated with it, if you get any questions or errors after clicking LAUNCHE WEBUI, they will be related to the WebUI itself and not this installer, so don’t ask or report them here , but here
• On the other hand, if you find a bug before that or have a feature request, please file an issue and more importantly join the new Automatic1111’s SD WebUI discord to discuss the project and get general help about WebUI
• ⚠️ This installer will always clone the latest bleeding edge update of the WebUI. Some updates may break it
